Cher’s reasoning for releasing “Dancing Queen,” which is due out in September, was simple.

“I’ve always liked ABBA and saw the original ‘Mamma Mia’ musical on Broadway three times,” she told Variety in an interview published Thursday. “After filming ‘Mamma Mia! Here We Go Again,’ I was reminded again of what great and timeless songs they wrote and started thinking, ‘Why not do an album of their music?’”

“The songs were harder to sing than I imagined but I’m so happy with how the music came out,” she added. “I’m really excited for people to hear it. It’s a perfect time.”

The Grammy and Oscar winner unveiled the track listing for “Dancing Queen” last month:

Her performance of 1976’s “Fernando” has been widely hailed by critics as a highlight of the movie, which reportedly raked in $77.9 million at the worldwide box office in its opening weekend.

Cher’s history with ABBA dates back to 2004. She appeared alongside all four members of the Swedish pop group ― Benny Andersson, Agnetha Fältskog, Anni-Frid Lyngstad and Björn Ulvaeus ― in a TV short called “The Last Video,” which was produced for that year’s Eurovision contest.
